Plantman Posted January 18, 2007 Report Share Posted January 18, 2007 Does any one knows which plants are suitable for outdoor pong in NZ climate? any plant name for suggestion? will they be the same in the north as it is in the south? can hygrophilia polysperma, ambulia or indica rotala be able to sustain the cold weather? :lol: :lol: :lol: Cheers Quote Link to comment Share on other sites More sharing options...
carla Posted January 18, 2007 Report Share Posted January 18, 2007 NZ climate goes from freezing Dunedin to subtropical Kaitaia. So where is your pond? In Auckland? And how cold does it get there in winter? Do you get frosts? Quote Link to comment Share on other sites More sharing options...
Plantman Posted January 18, 2007 Author Report Share Posted January 18, 2007 it was one of the questions post to me from trademe. i suppose i should say that ambulia, polysperma and indica would not survive in the winter. but i am not totally sure. i am in AUckland. i think at night the temp drop to 10 degree. but i have also heard that some of the member had had their plant growing in the pond. any care to share their experience? :lol: :lol: :lol: Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 18, 2007 Report Share Posted January 18, 2007 I know a guy who grows all three in an unheated glasshouse in Christchurch and they all all die off in the winter. They probably will not grow but might survive the winter in Auckland. Some plants will die off in winter but come away again from the roots in spring. Polysperma will if emersed but I don't know about submersed as it may rot. There are a lot of these plants sold by nurseries down here which would be realy struggling for most of the year. The easy answer would be that they are tropical plants---take the risk if you want. Quote Link to comment Share on other sites More sharing options...

fishboi Posted January 18, 2007 Report Share Posted January 18, 2007 i have ambulia growing out door in barrels for over 2 years but not very well. the barrels stay warm enough the lilys dont die off over winter. Quote Link to comment Share on other sites More sharing options...
Plantman Posted January 18, 2007 Author Report Share Posted January 18, 2007 True. But I remember seeing glossostigma and ludwigia repens growing wiildly in the stream of water. question is, will it survive in the pond? Quote Link to comment Share on other sites More sharing options...
fishboi Posted January 18, 2007 Report Share Posted January 18, 2007 if ur able to keep ur pond that clean i don't see why not. Quote Link to comment Share on other sites More sharing options...
Plantman Posted January 18, 2007 Author Report Share Posted January 18, 2007 so, it is not a questions about temperature but the up keeping of the water condition. http://www.tropica.com/productcard_1.asp?id=045a tropical spec says temperature from 15 degree. i bet the temperature in the stream is below 10 degree especially during the winter. i wonder if it is seasonal. they wither in the winter and grow again in the spring. Hm... Quote Link to comment Share on other sites More sharing options...

alanmin4304 Posted January 18, 2007 Report Share Posted January 18, 2007 Glosso is a native so will be OK, I am pretty sure there is a native eleocharis also but it is pretty tall-- grows on the west coast South Island. Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted January 18, 2007 Report Share Posted January 18, 2007 Your client could be like the rest of us playing poker-- you have to pay to look. I hate to think how much I have spent over the years finding these things out. Tell them to buy some and try-- then let us all know. Quote Link to comment Share on other sites More sharing options...
jn Posted January 18, 2007 Report Share Posted January 18, 2007 I have an outdoor pond in chch that grows ludwigia repens just fine in the winter. This particular pond is pretty neglected and the stuff does fine. Quote Link to comment Share on other sites More sharing options...
